Answer: For the graph,
43. y=2.5x−4
45. y=−15x+3
47. y=12x+−94
Step-by-step explanation:
43.
Let's solve for x.
y=2.5x−4
Step 1: Flip the equation.
2.5x−4=y
Step 2: Add 4 to both sides.
2.5x−4+4=y+4
2.5x=y+4
Step 3: Divide both sides by 2.5.
2.5x2.5=y+42.5
x=0.4y+1.6
Answer:
x=0.4y+1.6
45.
Let's solve for x.
y+15x=3
Step 1: Add -y to both sides.
15x+y+−y=3+−y
15x=−y+3
Step 2: Divide both sides by 1/5.
15x15=−y+315
x=−5y+15
Answer:
x=−5y+15
47.
Let's solve for x.
2x−3=4y+6
Step 1: Add 3 to both sides.
2x−3+3=4y+6+3
2x=4y+9
Step 2: Divide both sides by 2.
2x2=4y+92
x=2y+92
Answer:
x=2y+92
